drm/i915/tgl: Fix the read of the DDI that transcoder is attached to
On TGL this register do not map directly to port, it was already
handled when setting it(TGL_TRANS_DDI_SELECT_PORT()) but not when
reading it.
To make it consisntent adding a macro for the older gens too.
v2:
Adding TGL_PORT_TRANS_DDI_SELECT() so all future users can reuse it
(Lucas)
v3:
Missed parentheses arround val (Jose)
v4:
Renamed TGL_PORT_TRANS_DDI_SELECT to TGL_TRANS_DDI_FUNC_CTL_VAL_TO_PORT
(Lucas)
Added TRANS_DDI_FUNC_CTL_VAL_TO_PORT (Lucas)
